for downloaded authority zones. This fixes that the server
  could end up with malformed zone content after receiving
  truncated packet contents from an AXFR. In addition, the
  domain names in the SOA rdata are checked before the
  authority code picks up the zone serial.

W.C.A. Wijngaards 197a425c7d - Fix for iterator RCODE handling of YXDOMAIN. This fixes

2026-04-21 10:09:02 +02:00
W.C.A. Wijngaards 311054728d - Fix EDNS extended RCODE reflection. This fixes that

W.C.A. Wijngaards 6d74856212 - Fix for the Jiggle Attack. The server is fixed to answer
with errors for error cases, and does not stay silent.
  In addition, the error replies do not contain parts of the
  incoming query. This is more conformant, stops reflection
  and stops it as a covert channel. Thanks to Yuqi Qiu and
  Xiang Li, Nankai University (AOSP Lab) for the report.
  In addition, thanks to Qifan Zhang, Palo Alto Networks, for
  noting the fingerprinting possibility, that is also fixed
  with this.
